Abstract
Every day, a large amount of gas is consumed and transported through pipelines. Due to the irreparable consequences of the gas-related accident and their heavy financial losses, despite the company’s mission in the field, such as increasing the gas supply coverage, increasing customer satisfaction, and predicting emergency response plans, the safety of pipelines is one of the priorities of gas companies, government, and consumers. Hazard is part of every human endeavor, so hazard identification and risk management are critical. As some events may not be precisely predictable, the study of risk is critical. Risk management is a determinative step of the health, safety, and environmental management system (HSEMS). This study evaluates the performance of hazard and operability (HAZOP) analysis to assess hazards and risks for all processes present in Kermanshah Province Gas Company. Different risk analysis techniques include FMEA, JSA, and HAZID. As the HAZOP is a process hazard analysis that not only identifies system hazards but also determines their probability of occurrence by the effects of any deviations from design conditions and gives us accurate results, it is used for risk assessment in this project. This research is conducted by a team of three experts and identifies the process hazards by employing quid words. At the end of this study in Kermanshah Province Gas Company, about 282 risks are identified, only 03 risks are unacceptable, and 111 are conditional risks that must be eliminated without delay. The others are acceptable risks that must be eliminated but are not emergent.

Highlights

  • The safety of pipelines is one of the priorities of gas companies, government, and consumers;
  • The performance of the hazard and operability (HAZOP) method for assessing hazards and risks of all processes is studied;
  • Three experts conduct this research, and the process hazards are identified by employing quid words;
  • Two hundred eighty-two risks are identified, and only 03 risk is unacceptable; 111 are conditional risks that must be eliminated without delay; the others are acceptable that the risk must be eliminated but is not an emergency.
